IMPROVEMENT IN CHECK-VALVES FOR STAND-PIPES.

Specification forming part of Letters Patent No. 1131,9133, datedSeptember 10, 1872.

SPEoIEroATIoN.

To all whom it may concern:

Be it known that I, GEORGE W. HALLEN- BECK, Jr., of the city of NewYork, in the county of New York and State of New York, have inventedcertain Improvements in Check- Valves, of which the following is aspecificatio n, reference being hadto the accompanying drawing.

My invention consists in certain improvements in check-valves.

Figure 1 is. a vertical section of my improved valve; and Fig. 2 is asection view, showing the eccentric and the lower part of the stemdetached.

The object of my invention is to make a valve by which the water may bereadily discharged from' the pipe of a pump or similar apparatus. In thewinter it is often necessary to discharge the water from the pipe toprevent its freezing and thereby stopping the ilow of water or burstingthe pipe. With the ordinary valve the water could not be dischargedwithout unscrewing the valve, and when, as is commonly the case, thevalve is placed in the first or second story of the building, the waterwhich comes from the pipe is discharged on the floor, besides taking upconsiderable time and making a great deal of trouble. Besides, byrepeatedly unscrewing the joint the screw-threads become worn and thiscauses a leak. It is also necessary to let the water out when the pipesare to be repaired, and here, again, the joint of the valve would haveto be unscrewed. The pipes are generally painted or boxed up andfastened back against the wall. With the old valve it was necessary totear the pipe away from the wall to make any repairs. With my valve I doaway with all these objections.

In constructing my improved valve I pro vide a shell or case, A,provided with a valve, B, and guide I), as before. Below the guide b Iplace a shaft, 1), mounted at one end in a suitable bearing, 0, which-isscrewed in from the opposite side, and at the other end passing througha stuffing-box, F. This shaft is provided with an eccentric, O, as shownin Fig. 1, and in detail in Fig. 2, said eccentric being fastenedrigidly on the shaft, and provided at the end which extends outside ofthe case with a suitable handle, 6. The valve B is provided with a stem,asusual, which stem extends down or nearly down tothe eccentric 0 whensaid eccentric is turned down. When the handle E is turned in the properdirection the valve-stem a is raised by means of the eccentric 0,thereby allowing the water which is above the valve to escape downthrough the pipe into the cistern, well, or other place from which it isdrawn.

The advantages of this improvement are obvious. By it the water can atany time be let out of the pipe and thus prevent freezing and whennecessary to repair the pipes the water can be let out without floodingthe apartments. It is extremely simple and cheap.

I am aware that eccentrics have been used in faucet-s for operating avalve, and, therefore, I do not claim such; but-- What I do claim is Thearrangement, in a stand-pipe, of the valve B and eccentric G, as and forthe purpose herein set forth.
